Chicken Veggie Rice Casserole is a protein packed, easy one dish meal that's perfect for busy nights. With precooked chicken, green bell pepper and more in a simple, savory homemade sauce (that's topped with buttery breadcrumbs), this kid approved chicken dinner is a winner-winner every time!

Chicken Veggie Rice Casserole has many basic, staple ingredients that come together nicely to create a great meal. Cooked rice and leftover/precooked chicken are mixed with diced green peppers, onions, celery and pimentos for a colorful, textured variety.
Rather than using a can of condensed soup (as found in many casseroles), we make our own sauce with a bouillon packet, seasonings and mayo (trust me, it works).
And of course this casserole wouldn't be complete without some buttered breadcrumbs on top! Yum!

Serve it with garlic bread or cornbread, plus a side salad, and dinner is done!

👪Why you'll love it
| Prep time cut in half- Precooked chicken makes this meal a breeze. After you chop the veggies and cook the rice (heck, you could even use instant if you wanted to), there's not much more to it--other than mixing a few extras, making the topping (which is super easy) and popping it into the oven. Low maintenance- It doesn't get much easier than this. Isn't that the true beauty of a casserole? Once the work is done, it bakes in the oven and leaves you alone until the timer goes off, giving you ample time to catch up on your favorite Netflix show! Highly customizable- Love different kinds of peppers?--Add some. Big on seasoning?--Toss more in. Like wild rice instead?--Swap it. I think you get the idea. |

🥘Ingredients
- cooked rice- I typically use long grain white rice, but wild rice would also be good in this
- precooked chicken- may also use rotisserie or leftover turkey
- green pepper- you can switch this out for yellow or orange for more color variety
- onion- I like Vidalia for sweetness
- celery- kids love the crunch of this in the dish!
- diced pimentos- for added color and taste
- 1 packet granulated chicken bouillon- equivalent to 1 cube; I like buying it this way because you don't have to break it up
- reduced fat mayonnaise- I recommend Hellman's or Duke's
- salt and pepper- seasonings for the sauce
- butter & Italian bread crumbs- for the tasty topping
🔪Instructions

- Step 1: Combine cooked rice, cooked chicken, green pepper, onions, celery and drained pimentos in large bowl.

- Step 2: Make the sauce, then gently fold into the chicken mixture.

- Step 3: Place in a well greased 13x9 baking dish.

- Step 4: Mix the breadcrumbs and butter; sprinkle over the casserole and bake.
Hint: Don't overcook the rice! If it's too dry from overcooking, it won't be able to absorb the sauce.
🥣Substitutions
- protein- use leftover turkey or pork instead of precooked chicken
- rice- choose brown rice for a healthier option
- mayo- use plain Greek yogurt instead of mayonnaise
- topping- use crushed Ritz crackers instead of breadcrumbs
